How to create one line logs for each ID based on the result?

[junam2]

Is your feature request related to a problem? Please describe.
The results of inferences are not recorded in the log at once, so it is difficult to compare or search for the history of inference times for each model. Currently, the trace output varies widely by category (e.g., HTTP_RECV_START, INFER_RESPONSE_COMPLETE, HTTP_SEND_END), and additional work (like json parsing) is required to calculate the total time.

The --log-verbose option generates too many logs for one request.

Describe the solution you'd like
I would like to obtain the results of input token / output token / inference time / output_text for each ID in one line. (Like vllm, tgi)

Additional context
